#define EVID_TRINAT
 

As soon as the Midas header is striped out from the event, the YBOS remaining data has lost the event synchonization unless included by the user. It is therefore necessary to have a YBOS bank duplicating this information usually done in the FE by creating a "EVID" bank filled with the Midas info and other user information.

Unfortunately the format of this EVID is flexible and I couldn't force user to use a default structure. For this reason, I'm introducing a preprocessor flag for selecting such format.

Omitting the declaration of the pre-processor flag the EVID_TRINAT is taken by default see Midas build options and operation considerations.

Special macros are avaialbe to retrieve this information based on the EVID content and the type of EVID structure.

The Macro parameter should point to the first data of the EVID bank. 

  // check if EVID is present if so display its content 
  if ((status = ybk_find (pybos, "EVID", &bklen, &bktyp, (void *)&pybk)) == YB_SUCCESS)
  {
    pdata = (DWORD *)((YBOS_BANK_HEADER *)pybk + 1);
    pevent->event_id      = YBOS_EVID_EVENT_ID(pdata);
    pevent->trigger_mask  = YBOS_EVID_TRIGGER_MASK(pdata);
    pevent->serial_number = YBOS_EVID_SERIAL(pdata);
    pevent->time_stamp    = YBOS_EVID_TIME(pdata);
    pevent->data_size     = pybk->length;
  }

The current type of EVID bank are:

  • [EVID_TRINAT] Specific for Trinat experiment. 
      ybk_create((DWORD *)pevent, "EVID", I4_BKTYPE, (DWORD *)(&pbkdat));
  *((WORD *)pbkdat) = EVENT_ID(pevent);     ((WORD *)pbkdat)++;
  *((WORD *)pbkdat) = TRIGGER_MASK(pevent); ((WORD *)pbkdat)++;
  *(pbkdat)++ = SERIAL_NUMBER(pevent);
  *(pbkdat)++ = TIME_STAMP(pevent);
  *(pbkdat)++ = gbl_run_number;                // run number
  • [EVID_TWIST] Specific to Twist Experiment (Triumf). 
      ybk_create((DWORD *)pevent, "EVID", I4_BKTYPE, &pbkdat);
  *((WORD *)pbkdat) = EVENT_ID(pevent);     ((WORD *)pbkdat)++;
  *((WORD *)pbkdat) = TRIGGER_MASK(pevent); ((WORD *)pbkdat)++;
  *(pbkdat)++ = SERIAL_NUMBER(pevent);
  *(pbkdat)++ = TIME_STAMP(pevent);
  *(pbkdat)++ = gbl_run_number;                // run number 
  *(pbkdat)++ = *((DWORD *)frontend_name);     // frontend name 
  ybk_close((DWORD *)pevent, pbkdat);
